M. MANIMEGALAI AND S. UMAVATHI

Abstract

Methanolic extract of Kirganelia reticulata leaves were evaluated for the larvicidal and adult emergence inhibition activity against human filarial vector Culex quinquefasciatus. The rate of mortality was observed after 24 hours using the concentration of 0.1-0.5% and the values of LC50 and LC90 were tabulated by the method of Finney (1971). Qualitative analysis of the phytochemicals of methanol extracts revealed the presence of alkaloids, flavonoids, glycosides, steroids, phenols, tannins, saponins carbohydrate and protein. In this research it was revealed that the plant Kirganelia reticulata having the larvicidal properties and it can be used as a natural biocide against the filarial vector Culex quinquefasciatus.
